Hi everone!

I am trying to understand how the memory is implemented in DosBox. Reading on the Internet, I realized that there are two kinds of memory: low memory and high memory. The former is a non-configurable 1mb memory, the latter is a configurable memory (max 64mb but not recommended bigger than 32mb).

Apparently (checking memory.cpp) just the high memory is used. Can does anyone explain me the difference between them and where are them used?

Thank you in advance!
